一般描述
Caspase-1, also known as IL-1 beta-converting enzyme (ICE), is an enzyme that cleaves the inflammatory cytokines IL-1 beta and IL-18, releasing the mature, active peptides. Caspase-1 is important for defense against pathogens and it also is involved in the induction of apoptosis. Thymocytes from caspase-1 deficient mice are resistant to Fas-mediated apoptosis, and caspase-1 is similar to the cell death gene CED-3 of C. elegans. Caspase-1 is a heterotetramer that consists of two anti-parallel heterodimers, each one formed by a 20 kDa (p20) and a 10 kDa (p10) subunit. The enzyme has a preferred cleavage site of Tyr-Val-Ala-Asp (YVAD). Caspase-1 is highly expressed in spleen and lung, and is absent from brain.
特异性
This antibody recognizes the p20 subunit of Caspase 1. This antibody may cross-react with Caspase 5 due to 92% sequence homology. Additionally, this antibody recognizes the P45 proenzyme (~45 kDa) and the p20 subunit (~20 kDa) of the reduced, human Caspase 1 isoforms.
Other homologies: Mouse, rat, canine, porcine and feline. (92% sequence homology).
免疫原
KLH-conjugated linear peptide corresponding to the p20 subunit of human Caspase 1.
Epitope: p20 subunit
应用
Immunohistochemistry Analysis: A 1:1,000 dilution from a representative lot detected Caspase 1 in human spleen tissue. Additionally, a 1:4,000 dilution from a representative lot detected Caspase 1 in human colon tissue.
Anti-Caspase 1 Antibody is a highly specific rabbit polyclonal antibody, that targets Caspase 1 & has been tested in western blotting & IHC (Paraffin).
